Mikel Arteta is set to be without both Gabriel Jesus and Thomas Partey for the “next few weeks”.
Jesus limped off with what looked to be a hamstring injury after assisting and then scoring in Arsenal’s 2-1 Champions League win over Sevilla in midweek.
“The scans show that there is a muscle injury. We might miss him for a few weeks again,” Arteta said.
“With Gabi I cannot give you any time frame because he always surprises us.
“He felt something there, it was a really awkward action. It’s true that he had quite a lot of load in those games playing with the national team and with us which he hasn’t done in a long, long time.
“That’s really bad news for us.”
Partey, meanwhile, has been dealt another setback after suffering a muscle injury which forced him to miss the game with Sevilla.
“He’s got a muscle injury and we expect him to be out for a few weeks,” Arteta said when asked about Partey.
“We don’t know the extent of it still, he has more tests today. He got that injury in training, with the last kick of the ball. Very unfortunate.
“He was coming from a period of absence and he needed minutes. He played with the national team. We try to be in touch with them always.
“Then we had two games very close with Chelsea and Sevilla. We decided not to load him in Chelsea and play him in Seville, and then it happened in training.
“So, sometimes it’s difficult. We try to prevent it. If he had got injured against Chelsea or against City you
would have said we rushed him and then we don’t and he gets injured. It happens. That’s football.”
